2 Kings 2:23-24 

“From there Elisha went up to Bethel. As he was walking along the road, some boys came out of the town and jeered at him. ‘Get out of here, baldy!’ they said. ‘Get out of here, baldy!’ He turned around, looked at them and called down a curse on them in the name of the LORD. Then two bears came out of the woods and mauled forty-two of the boys.”

Elisha is a prophet of God—and apparently not a man you want to mess with. When some boys call him bald, he curses them and two bears come and maul 42 of them. This seems a little excessive, but I can think of a bald man or two to whom this would seem perfectly reasonable.
